2021-10-25 05:03:24

VANCOUVER, BC / ACCESSWIRE / October 25, 2021 / Diamond Fields Resources Inc. (TSX-V:DFR) (“DFR” or the “Company”) is pleased to announce a maiden Mineral Resource prepared in accordance with National Instrument 43-101 (“NI 43-101”) for Moydow Holdings Limited’s (“Moydow”) Labola Gold Project in Burkina Faso (“Labola” or the “Project”). As described in the press release of August 25, 2021 (the “Initial News Release”), DFR has entered into definitive agreements to acquire Moydow which has an option to own 100% of the Project (the “Transaction”).

Highlights (See Table 1 and Figures 1-3)

  • Indicated resource of 5.41 million tonnes at an average grade of 1.52 g/t Au for a total 264,000 ounces of gold; and

Inferred resource of 6.93 million tonnes at an average grade of 1.67 g/t Au for a total of 371,000 ounces of gold.

  • The Mineral Resource Estimate (MRE) was estimated using ordinary kriging methodologies, standard estimation practices and constrained by an open-pit evaluation based on a US$1,900 per ounce gold price and reported using a cut-off grade of 0.5 grams of gold per tonne (“g/t Au”).
  • The MRE is based upon a total of 69,787 metres (“m”) of drilling from 566 drill holes which includes the recent Moydow, confirmatory, twin and infill drilling of 4739m for 31 holes (23 twin holes).
  • Three mineralized zones have been outlined from the various drilling programs and each zone is open in all directions. Extensive target generative work demonstrates many opportunities for resource expansion which include extensions to the current pit constrained resources; zones with only widely spaced drilling; extensions of known mineralized zones with no drilling; untested artisanal sites and potentially new mineralized zones indicated by geophysical and geochemical anomalies.
  • The Company’s future exploration and development programs, following completion of the Transaction as defined in the DFR press release of August 25, 2021, will focus on resource expansion opportunities with a view to producing an updated MRE and completion of a Preliminary Economic Assessment.

“The completion of the maiden Mineral Resource is a major milestone in the progression of the Labola Project and is a testament to the work completed by the Moydow technical team over the last year. The positive results contained in the Mineral Resource Estimate confirm our belief that Labola is a highly prospective project and an exceptional opportunity for future development. Labola is a project with shallow, open pit resources of which 41% of those currently delineated are in the Indicated category. The Project has over 30 km of potential strike length along three mineralized zones and many walk-up drill targets which will enable rapid resource expansion. DFR would acquire, in addition to the maiden Mineral Resource, an extensive database of historical information which will allow the Company to add value directly through the drill bit and supporting technical studies as we progress along the pathway to further development of the project” commented Al Gourley, Chairman of DFR.

The Transaction, as defined in the Initial News Release, is subject to approval by the TSX Venture Exchange, required shareholder approvals, and completion of satisfactory confirmatory due diligence by DFR. The Transaction remains expected to close in the first quarter of 2022.

  1. ** Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, marketing, or other relevant issues. The Mineral Resources in this note were reported using CIM (2014) Standards on Mineral Resources and Reserves, Definitions and Guidelines and adopted by CIM Council.
  2. ^The quantity and grade of reported the Inferred Resources in this estimation are uncertain in nature and there has been insufficient exploration to define this Inferred Resource as an Indicated or Measured Mineral Resource. It is uncertain if further exploration will result in upgrading the Inferred Resource to an Indicated or Measured Mineral Resource category.
  3. The Mineral Resource has been constrained by an open pit evaluation using a gold price of $1900 per ounce, and then reported at a cut-off of 0.5 g/t Au.
  4. Contained metal and tonnes figures in totals may differ due to rounding.

Moydow has estimated the amount of the resource that has been depleted by artisanal mining to be approximately 341,000 tonnes at 3 g/t Au. The quantity of mined material has been calculated from estimates of dump and leach pad volumes. The grade of the material mined has been estimated in the range of 1.5-3.0 g/t Au and is based on an evaluation of extensive rock chip, channel sampling of artisanal workings and selective sampling of adjacent dumps. The location of where the material has been mined from is not known with any degree of accuracy. As such, the artisanal mining has not been deducted from the Mineral Resource but noted here for reference.

Preliminary metallurgical results from historical metallurgical samples, supported by extensive LeachWELL (proprietary accelerated cyanide leach technique) data from Moydow drilling samples, indicate that gold is readily treatable by conventional cyanide leaching techniques after grinding to industry standard grind-sizes of approximately 80% passing 120 microns. Recoveries are in the range of 90% and 98% in the oxide zone and between 82% and 93% in the transition/sulfide zone.

The mineral resource estimate (MRE) for the Labola Project has been prepared by Mr. Ivor W.O. Jones, M.Sc., FAusIMM, P.Geo, of Aurum Consulting, who is an independent Qualified person (QP) under NI 43-101 guidelines. The maiden Mineral Resource and its preparation will be detailed in a technical report prepared in accordance with NI 43-101 to be filed on SEDAR within 45 days of this press release.

The MRE has been prepared using grades with top-caps applied in a fairly standard grade ordinary kriged estimation. Holes that had been twinned were removed, and replaced with the new drill data, but estimates also cross-checked with just the old data with very similar results. This provided significant confidence in the historical data. Validation included visual and statistical evaluations and considered to be good. Classification of the MRE was based on the guidelines of the CIM and NI 43-101 to define and report Indicated and Inferred Resources for the project.

About Labola

The Labola gold exploration project is in the Banfora greenstone belt of the West African Birimian Supergroup in southwest Burkina Faso. Labola is approximately 450km west-southwest of the capital, Ouagadougou, and 100km northeast of the Wahgnion gold mine, operated by Endeavour Mining (Q2, 2021 production of 41 000 ounces gold).

More than 65,500m of historical drilling (541 holes) has been completed across multiple drilling campaigns by previous owners, High River Gold Mines Limited (“HRG”), later acquired by Nord Gold Plc, and Taurus Gold Limited (“Taurus”), consisting of principally diamond and RC drilling (24,589m/39,339m, respectively). Mineralization has been intercepted by historical drilling and outlined by previous artisanal mining in three main zones over a 10 km strike length.

Moydow has explored the area since August 2020 including acquisition and compilation of all previous data into a single database, interpretation of this data, target generation using the database and all the acquired remote sensing information, a drilling program involving 23 twin holes and an additional six exploration and infill holes. The database of historical information has been audited, correctly coordinated and the twin drilling results demonstrate the validity of the previous data. The results of the Moydow drilling showed strong reproducibility of the HRG and Taurus drill data in both terms of location of mineralization and grade. Further, the brownfields exploration drilling showed good predictability of the location of mineralization in extensional drilling to the mineral resource. The HRG, Taurus and Moydow data was therefore taken as sufficiently accurate to be used in the estimation of the Maiden MREs for Labola.

Gold mineralization at Labola is related to quartz veining, areas of silica alteration and disseminated pyrite. A previous ground IP survey highlighted the coincidence between mineralized zones and high chargeability (sulfides) and resistivity (quartz veining and silicification) anomalies. This correlation outlines many additional opportunities for resource expansion drilling in the future.

In addition to the preparation of the maiden MRE, Moydow has compiled, integrated, and assessed all the available information and outlined future exploration targets based on each of the main data sets. Based on this, Moydow selected targets and ranked them based on their perceived proceptivity as summarized:

  • Priority 1 – Taurus Resource Targets.
  • Priority 2 – HRG Resource Targets.
  • Priority 3 – Mineralization Extensions.
  • Priority 4 – Untested Workings.
  • Priority 5 – Previous Drill Intercepts.
  • Priority 6 – IP Targets.
  • Priority 7 – Mineralization Trends.
  • Priority 8 – Geochemical Targets.
  • Priority 9 – EM targets.

The main targets are along the major interpreted central shear system encompassing the three mineralized zones. There is also strong evidence that there are several sub-parallel, additional structures that also host significant gold mineralization as shown by artisanal workings. These targets can be considered as clearly defined for drill testing. Many of the targets are resource expansion opportunities as they are obvious extensions to identified resources and include areas with only widely spaced historical drilling. Additional targets include untested zones with artisanal workings and new zones as defined by soil geochemistry and/or Induced polarization surveys. Labola therefore represents an advanced exploration project with clearly defined drill targets that provide opportunities for exploration and resource expansion.
